SPECIFICATION forming part Of Letters Patent N 0. 729,070, dated May 26,1903.

Application filed July 24,1902. Serial No. 116,761. (No model.)

To all whom, it may concern:

Be it known that I, RAYMOND H. HORN- BROOK, a subject of the King ofGreat Britain, residing at Canton, county of Stark, and State of Ohio,have invented a new and useful Steam-Condenser, of which the followingis a specification.

My invention relates to an apparatus for condensing steam by passing itthrough relatively small tubes and cooling the same by currents of air,either dry or moistened,which process is made the subject of anotherapplication for patent; and the object of this invention is toaccomplish the condensation by an induced draft around and among thetubes. I attain this object by the apparatus and mechanism illustratedin the accompanying drawings, in which Figure'l is a plan view of thecondenser with the top of the case removed; Fig. 2, a verticallongitudinal section on the median line of the same; Fig. 3, across-section of an apparatus in which the tubes are staggered inreference to each other; Fig. 4, a crosssection of a corrugated tube;Fig. 5, a longitudinal section of a crimped tube. A

The tubes 1 are preferably made quite thin and of a metal which conductsheat readily, and at either end of the tubes are the plates 2, intowhich the tubes are securely fastened, To the tube-plate at one end issecurely joined, by bolts or otherwise, the head 3, forming thesteam-chamber 4, to which is connected the steam-pipe 5, and to thetube-plates at the other end is similarly joined the head 6, forming thereceiving-chamber 7, to which is connected the drain-pipe 8.

Steam-exhaust from an engine, a feed-water heater, or other sourcepasses into the steam-chamber through the steam-pipe, from which chamberit is distributed through the respective tubes wherein it is condensed,whence the water or Vapor accumulates in the receiving-chamber andpasses off through the drain-pipe to an air-pump, a vacuumpump, or otherreceptacle. To increase the surface of the tubes, they can belongitudinally corrugated, as shown in Fig. 4, or crimped, as shown inFig. 5.

The case 9 entirely surrounds the tubes and the chambers at either endthereof, and one end of the case, preferably corresponding to thesteam-chamber, is connected with the exhauster 10. The other end of thecase, preferably corresponding to the receiving-chamber, is left open.Depending from the top of the case are the respective deflectors orbaffle plates 11, which preferably extend downward to include the lowertubes, but not to the bottom of the case, and projecting from the bottomof the case are the respective deflectors 12, which preferably extendupward to include the upper tubes, but not i to the top of the case.Suitable apertures 13 are provided in the several deflectors for therespective tubes,whereby the deflectors serve as suitable supports forthe tubes at intervals along the case.

The top and bottom deflectors are located alternately along the case,preferably about 1 equal distances apart. Across the top of the case,preferably opposite the bottom' deflectors, are provided the ports 14,which can be opened and closed by doors or dampers, as 15, and acrossthe bottom of the case, preferably opposite the top deflectors, areprovided the ports 16, which can be opened or closed by doors ordampers, as 17. Sprayheads 18 are located in the open end of the case,through which heads small jets of wa ter can be distributed fromthe'water-pipes 19, and a spray-pipe 20 is conveniently located in andacross the case, preferably about its middle, through which pipe smalljets of water can be distributed from the waterpipe 21.

To operate the condenser, the fan 22 of the exhauster is set in motion,and a strong current of air is thus drawn into the case at its openend.Thiscurrentisconducted,asshown by arrows in Fig. 2, first against therecei ving-chamber, thence over the same and diagonally downward aroundand among and impinging the respective tubes and under the first topdeflector, thence diagonally upward around and among and impinging therespective tubes and over the first bottom deflector, and so on to andfro to the end of the tubes and over the steam-chamber, thence passingoutthrough the exhauster. The current of air is reinforced and cooled bysubcurrents, which are drawn in the case through the respective ports,as also indicated by arrows in Fig. 2, so that the induced air-currentis kept quite cool in its circulation around and among and impinging thetubes, even to the hot or the case and keep itcool to the end of thetubes, and instead of locating the respective tubes in rows oppositeeach other, as shown in Figs. 1 and 2, the tubes can be so disposed thateach tube in one row is opposite the space between tubes in the adjacentrow, .as shown in Fig. 3, thus exposing each individual tube more fullyto the cooling medium.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination of a steam-chamber connected with a steam-pipe, areceivingchamber connected with a drain-pipe, and relatively small tubesconnecting said chambers; a case surrounding said chambers and tubes,said case being open at one end and connected with an exhauster at theother end; and deflectors alternately depending from the top andprojecting from the bottom of said case, said deflectors havingapertures for said tubes to support the same.

2. The combination of a steam-chamber tubes, said case being open at oneend and connected with an exhauster at the other end; and deflectorsarranged to guide an air-current to and fro around and among said tubesto impinge the same.

3. The combination of a steam-chamber connected with a steam-pipe, areceivingchamber connected with a drain-pipe, and relatively small tubesconnecting said chambers; a case surrounding said chambers and tubes,said case being open at one end and connected with an exhauster at theother end; deflectors arranged to guide an air-current to and fro aroundand among said tubes to impinge, the same; and ports in said caseintermediate its ends.

4. The combination of a steam-chamber connected with a steam-pipe, areceivingchamber connected with a drain-pipe, and relatively small tubesconnecting said chambers; a case surrounding said chambers and tubes,said case being open at one end and connected with'an exhauster at theother end; deflectors arranged to guide an air-current to and fro,around and among said tubes to impinge the same; and means for sprayingwater in said case.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
